WALL MOUNTING
1. Place the heater unit against the wall in the position in
which it is intended to be installed.
2. Mark the mounting hole positions through the heater back
on to the wall (See figure 2).
3. Drill the wall at the marked centers. The hole size will
depend on the type of wall and fixing method. The heater
is supplied with #8 woodscrews and anchors suitable for
solid and plasterboard walls. These anchors require a ¼"
hole size.
4
. Secure the top connector plate to the wall using the
woodscrews (and anchors where necessary). See figure 3.
5. Place the heater unit back in position. Attach the heater top
to the connector plate with the two thread cutting screws
supplied.
If blower accessory VF171 or VFT171
is to be fitted
Connect blower in accordance with the instructions
supplied with the accessory. Attach the connector plate
through the two holes nearest the back of the heater (See
figure 4).
If blower accessory VF171 or VFT171
is not to be
fitted
Attach the connector plate through the two holes nearest
the front of the heater (See figure 4).
GAS CONNECTION
Gas connection is ½”NPT near the rear right corner.
The appliance is supplied fitted with an elbow connector. This
connector can be rotated to allow supply pipe connection from
the left or right side or from below the heater. For rear
connection, the pack includes an alternative straight connector to
replace the elbow.
The gas supply line must be sized and installed to provide a
supply of gas sufficient to meet the maximum demand of the
appliance (see specification table) without undue loss of
pressure
.
Always use pipe compound. Apply compound lightly to the
male threads to ensure excess does not enter gas lines. The
compound must be resistant to LP gas.
A plugged
1
/8in.NPT tapping should be installed upstream of
the connection to the appliance. The tapping should be
accessible for test gauge connection.
We also recommend the installation of a sediment trap upstream
of the appliance. This will trap any solid or liquid contaminants
which may otherwise enter the heater causing poor
performance.
Appliance shut-off valve (Figure 5)
This heater incorporates a shut-off valve. The valve is located at
the bottom front corner, at the upstream end of the pipe running
to the thermostat.
